What best describes the recessive allele?

The best description of a recessive allele is that in does not determine the phenotype when a dominant allele for the same trait is present.

What is recessive allele?

Recessive refers to a type of allele which will not be manifested in an individual unless both of the individual’s copies of that gene have that particular genotype.

How do you describe recessive gene?

A recessive gene is a gene that can be masked by a dominant gene. In order to have a trait that is expressed by a recessive gene, such as blue eyes, you must get the gene for blue eyes from both of your parents.

Which of the following describes a recessive trait?

A recessive trait is the weak, unexpressed trait of a dichotomous pair of alleles (dominant-recessive) that has no effect in the phenotype of heterozygous individuals.

How would you best describes recessive allele quizlet?

What is recessive and dominant allele?

Dominant refers to the relationship between two versions of a gene. Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked.

What is recessive allele Class 10?

If the alleles (two versions of each gene) of a gene are different, one allele will be expressed as Dominant gene while the other allele effect is called recessive.

What is an example of a recessive allele?

Examples of Recessive Traits

For example, having a straight hairline is recessive, while having a widow’s peak (a V-shaped hairline near the forehead) is dominant. Cleft chin, dimples, and freckles are similar examples; individuals with recessive alleles for a cleft chin, dimples, or freckles do not have these traits.

How is a recessive allele different from a dominant allele?

A dominant allele produces a dominant phenotype in individuals who have one copy of the allele, which can come from just one parent. For a recessive allele to produce a recessive phenotype, the individual must have two copies, one from each parent.
